描述 Description

ASM1442K is the next generation high speed TMDS level shift ICs for High Definition Multimedia Interface (HDMI) and Digital Video Interface (DVI) video application, supporting the feature oif Deep Color and 3D video format and high video 4K resolution. Those convert low-swing AC-coupled differential input from existing PCI Express in the chipset of PC to HDMI compliant differential output, supporting up to 3.4 Gbps bandwidth of pixel data transition, as indicated in HDMI Rev1.4b. This conversion is automatic and transparent to the user. The devices operate at a single 3.3V supply.
